Colorful unveiled its flagship socket LGA2066 motherboard, the iGame X299-X. Characterized by its milky-white PCB and matching white PCH and VRM heatsinks, and I/O shroud, with red+black accents, and the opposite color combination, the board is halfway between ATX and E-ATX. It draws power from a combination of 24-pin ATX, 8-pin EPS, and 6-pin PCIe power connectors, conditioning it for the CPU with a 10-phase VRM. The socket is wired to eight DDR4 DIMM slots, and four PCI-Express 3.0 x16.

Storage connectivity on the Colorful iGame X299-X includes two 32 Gb/s M.2 slots, and six SATA 6 Gb/s ports. USB connectivity includes two USB 3.1 ports on the rear panel (including one type-C), ten USB 3.0 ports (six on the rear panel), and input-device optimized USB 2.0 and PS/2 ports. The board features two GbE interfaces driven by Intel controllers, and high-grade onboard audio with a 120 dBA SNR CODEC, and audio-grade capacitors.
